The current ongoing & future re-engineering of the entire SAP product suite to SOA - Service Oriented Architecture based principles as well as emergence of On-Demand Software Delivery will naturally lead to significant implications for SAP financial investment decisions as well as their business partner ecosystem.

Organizations are advised to stagger their SAP investment decisions on a Just-In-Time Need-To-Invest-Now basis to ensure that they are protected from future obsolescence and benefit from SOA & SAAS led business model transformations.

Also, the ongoing financial meltdown induced recession has prompted many organizations to start seeking savings from their SAP investments.

SAP's SAAS Architecture - Between the 2 basic SAAS architecture options of Multi-tenancy (where multiple organizations share a single instance of the application and database) and Isolated Tenancy (which has individual hosted application and database instances for each customer), SAP's Software On Demand works on the latter option.

SAP also plans to offer customers options to move from on demand solutions to on premise solutions at a later stage.
